please solve questions qnd ahow all code and work matlab only

Write a MATLAB function y= func 3(x) which implements the equation f(x)=0.5x34x2 +6x2=0. It will be used by the Newton-Raphson method M file. Use the MATLAB implementation of Newton-Raphson method to find a root of the function f(x)=0.5x34x2 +6x2=0 with the initial guess x0=4.5. Perform the computations until percentage approximate relative error ((a(%)) is less than (a=1%. You are required to fill the following table. Now run the same routine with the initial guess x0=4.43 instead of 4.5. Perform the computations until percentage approximate relative error ((a(%)) is less than (a=1%. You are required to fill the following table
